Patented Dec. 20, 1949 UNITED STATE-S PATENT OFFICE WINDOWY Jack A. Walde, San Mateo,- Calif.` Application September 30, 194:6', Serial No. 70052491 (Cl. 2li-5.6.4)

4 Claims.

1i Thisinvention relates to ani apparatus for hold.` ing window panes in position.I ina window frame; The; objects of. this. invention are to provide a stormftight sash assembly in which the panes,

areremovable and, replaceable from one side of the window frame; to provide a type of spring` metal latch for holding a. Window in, position and permitting removal of tghewindow-pane without removal. of the latch; to provide a spring metal window latch whichwill be visually unobtrusive and o f pleasing appearance; to provide a weather-tight window including a superior weather-tight gasket; and to provide a: type; of window especially suitable for standardized mass production for prefabricated houses and other standard size windows.

Another object of the invention isA to. facilitate removal of window pane either for cleaning, removal of paint or for renewal.

Other objects and advantages of this invention will appear in the Course of the following. de# scription.

In. the drawing:

Fig. 1 is a front elevation of a Window embodying this invention;

Fig. 2 is a side elevation in section along the line 22 of Fig. 1;

Fig. 3 is a side elevation in section showing an alternative form of latch; and

Fig. 4 is a detail showing the cross-section of an installed gasket.

Referring to the drawings, it will be seen that the sash I can be made either stationary or hung vertically, horizontally, or from a hinge. It is preferable that the openings for the glass or other panels include a flat surface I I on which the gasket I2 is secured, an edge I3 to retain the window pane Within limits, and an additional indentation or recess I4.

The latch I5 consists of strip-like sheet spring metal or plastic held to the sash I0 by a screw, rivet, or nail I6. At the edge of the sash opening the latch is bent at I'I and extends toward the window pane I8. It is bent again at and terminates in the short foot portion 2l, which preferably should be no longer than the width of the indentation at I4. The foot portion 2i is sloped so as to apply pressure to the pane I8 to urge it into good sealing Contact with the gasket I2.

Since the latch I5 is made of spring material, a window pane I8 may be installed by simply pressing it into the frame opening or by pressing the portion I9 with the thumb until the end of short portion 2l touches the edge of the indentation at I-.4.. 'Iheiwndow pane I8 is: then placed into the sash opening and rests on the gasket I2. When the! pane I8 is; in place, the latch is released, and the.` foot portion 2|. of. the latch bears against the edge: of the window pane. I8 holding it firmlysealedI against the gasket; I2.,

The latch I5V whichahas been described. above isl preferably installed alongV thel outside edge. of the sash.. For the portion of the window frame Where there are adjoining. panes (as in the. lower half of Fig. 2 or the center portion of the', frame in Fig. l), there could be two such latches I5, each one holding one pane. Howeverthe preferable treatment in this case, as shown in the bottom` portion of Fig. 2, is to use thelateh 22, in which there is a center portionheld in a manner similar to the way the latch I5 was held and where there. are spring arms I9.- on either side. The:` operation of the double latch 2-2 is in al1 respects the same as that of the latch I5.`

An alternative form of latch 23 is shown in Fig. 3, where instead of the sha-rp corner I1 shown.A inr latches I5y and 2-2, there is.v an arcuate bend 24 raising the latch 23 away from the sash I0 in the Vicinity of the sash edge. Just as latch 22 is a special form embodying the same principles as latch I5, so there can be made a latch of the type of latch 22 containing two arcuate bends 24, each similar to the one on latch 23.

In Fig. 4 is shown an enlargement of one form of gasket I2 placed in position. This gasket I 2 is made of rubber or some other resilient material. Preferably it is made of one piece for the four edges of the window, as can be readily done where these gaskets and latches are mass produced for standard sized openings. However, each gasket may be made in four strips or in one continuous strip bent around at the time of installation. The gasket I2 may be held in place by gluing it or cementing it to the edge of the frame II, or it may be held in by nails or tacks, as at 25, distributed along portions of the gasket.

The specific form of the gasket as shown in Fig. 4 is not necesary to produce a weather-tight window in this invention. However, the type presented is of special interest as representing an ideal form of such gasket. The long arm 26 is compressed by the pane against the raised portion 2I and the pressure is thus distributed on the gasket at two points: (1) where the projecting arm 26 of the gasket joins the main portion of the gasket I2; and (2) at the point where the arm 26 rests on the raised portion 21. Thus this gasket has an advantage over an ordinary 5.5 i'lat gasket by presenting a better sealing member and also is an improvement over a type of gasket where there would be an arm 26 but no raised portion 21 so that although there might be satisfactory sealing there would be no division of pressure, and the force on the point where the arm 26 meets the gasket I2 would tend to break 01T the arm 26.

It can be seen that this type of window installation can be made inconspicuous or can be made in a design which will enhance the beauty of the window frame. Although it might be installed along all four sides of the window pane, it is not necessary to do so, for installation of the latch along two sides is suflicient, since pressure on two sides will hold the window against the gasket on all four sides. As shown in the drawing in Fig. 1, the latches are preferably installed along the horizontal edges of the panes. Although this has some advantages, the latches could also be installed along the vertical edges. Similarly they may be installed on the outside of the Window frame instead of on the inside if that should be desirable.

It will be apparent that there are other equivalent forms in which the latches l5, 22, and 23 could be made without departing from the spirit of this invention, and throughout the invention there may be changes, apparent to persons learned in the art, in size, material, form, and

other matters which still would not depart from the spirit of this invention or from the scope of its claims.

I claim:

1. A Window construction including a frame, an opening in said frame, having a flange with a sealing gasket thereon, a pane in said opening, a resilient pressure member secured to the edge of said opening, said pressure member having a foot portion applying pressure along the edge of said pane to press it' against said gasket, said frame having a recess to receive said pressure member when it is depressed While inserting or removing said pane.

2. The window construction claimed in claim 1, in which the gasket comprises a forked strip having a lower heel portion which ts on said ange, said heel portion having a mound extending lineally and parallel to the fork of said strip, said forked strip also having an upper arm portion projecting from said fork further than the distance from the fork to the mound, so that said arm portion rests on said mound when pressure is exerted on it by the pane and the resilient pressure member.

3. A window construction including a frame having an opening therein and a flange with a sealing gasket thereon, a pane in said opening, a strip metal spring latch member secured to said frame along any two opposite edges of said opening, said latch member having a foot portion applying pressure along the edge of said pane to press it against said gasket, said frame having a recess to receive said latch member when it is depressed While inserting or removing said pane.

4. A window construction including in combination a frame having an opening and a moulding around said opening having two successively stepped-in flanges, a resilient gasket fastened to the flange immediately Vadjacent to said opening, a pane in said opening and resting on said gasket, and a resilient pressure member secured to said frame adjacent to the edge of said opening and having a foot portion applying pressure along the edge of said pane to press it against said gasket and being adapted to t into the space above the ange farther from the opening when depressed While inserting or removing said pane.
